Abstract
A bladder device is for moving a component of a web packaging machine that forms and encloses a food product in a food product package made of webs of packaging material. The bladder device has a bladder and a nipple stub coupled to the bladder and having a first end configured to receive a gas and a second end configured to dispense the gas into the bladder to thereby inflate the bladder and move the component of the web packaging machine. A collar coupled to the nipple stub such that the bladder is sandwiched between the collar and the second end of the nipple stub. The second end of the nipple stub has a depression and the collar has a boss that is oriented towards the depression such that tightening the collar on the nipple stub forces the bladder into the depression and thereby forms a fluid tight seal.
